SPECIFICATION forming* part-of Letters Patent No. 283,085, dated `August14, 1883.

Application iiled September 27, 1882. (No model.)

Be it known that I, JAMES H. DUKE, a citizen of the UnitedStates,residingat Jackson, in the county of Butts and State of Georgia, haveinvented certain new and useful Improvements in Churns; and I doherebydeclare that the' following is'a full and exact description of thesame, reference being had to the annexed drawings, making apart of thisspecification, and to the letters and figures' Of reference markedthereon.

Figure l of the drawings is atop plan view of my invention,` Fig. 2 aside elevation, partlyv in section; and Fig. 3 a detailview of one ofthe dashers. Y i

The present invention has relation to certain new and usefulimprovements in the driving-power of double-acting churns; and itconsists in the details Of construction, Asubstantially as shown in thedrawings, hereinafter described and claimed. 4

In the accompanying drawings, A repre-` sents a suitable frame havingcross-beamsa, which serve as bearings for the journals of oscillatingshafts B B. These shafts, upon their inner side, have slotted arms C, towhich arepivoted the upper ends Of dasherrods b. These rods bhaveconnected to them the usual pins, c, extending radially along theirlength, to agitate the cream contained in the churn-cylinder C, saidrods having atI their lower ends `dashers d. A cover, e, iits over ,thetop of the cylinder C', and is held thereon by a curved spring.- rod, D,the notched end e thereof` entering a slot in the upright f, while thebearing g bears against a shoulder, g', upon the side Of an upright, l1,whereby said rod is sprung On the churn-cover tO hold it in position. y

Vhen it is desiredto remove the cover the handle end 'i of the rod D is.pressed down. suiiciently to be disengaged with the shoulder g, afterwhich the opposite end is withdrawnfrom the post, or upright f, thusallowing the cover to be raised.

A very simple `and effective means of securely holding the cover inplace while churning is obtained without aid of the usual complicatedfastenings.

Upon the under. side of the shaft B, near one end thereof, is adepending perforated vertically-vibrating slotted arm, E, to which ispivoted one end of a perforated adjustable l pitman, F. The opposite endOf the pitman F is pivoted in like manner to aperforatedvertically-vibrating slotted arm, G, depending from the shaft B. To theopposite end of the shaft B is another depending perforatedvertically-vibrating slotted arm H, to which is pivoted one end of anadjustable pitman, I. The pitman, at its other end, is suitably coninthesides of the frame A. One end of this crankshaft extends beyond the sideof the frame, and has rigidly connected to it a suitcord, m. This beltor cord passes over a drivewheel, 4K, which is larger than the pulleyI,Y

secured to one end of a suitable shaft, n.,

which has its bearings in bones19. It will be seen that by raising orlowerin the ends of the pitmen vertically with relaeach dasher may beregulated independent o'f the other, thereby enabling a variety ofchanges jin the motions of the two dashers tO be made when churningcream of different grades -Or qualities. A

The oscillating. shafts, with ltheir slotted arms for connecting thedasher-rods and pitmen, are not only effective as a driving-power `forchurns, but provide a dri-ving mechanism that is both strong anddurable.

Having now fully describedmy invention, what I claim as new, fand desireto secure by Letters Patent, is#- ing the oscillating shafts B B',carrying the slotted arms C C for .attaching the dasherrods' l), b,andthe depending slotted vertically-vibrating arms E G H, of theperforated pitmen F I, the former engaging the arms E- G, and verticallyadjustable therein,

the arm H, and its other end connecting the crank-shaft 7c, as shown anddescribed.

' In testimony that I claim the above I have hereunto subscribedmy namein the presence of two witnesses.
